The potential for hemolytic disease of the newborn occurs when ________.

Question

Quizplus · Accepted Answer

Hemolytic disease of the newborn occurs when fetal Rh⁺ cells enter an Rh⁻ mother, causing her to produce antibodies against the Rh factor. These antibodies can cross the placenta and attack the red blood cells of a subsequent Rh⁺ fetus, leading to hemolysis and other complications. Maternal Rh⁺ cells entering an Rh⁻ fetus, maternal Rh˗ cells entering an Rh⁺ fetus, and fetal Rh˗ cells entering an Rh⁺ mother do not result in hemolytic disease of the newborn. Fetal Rh⁺ cells entering an Rh⁺ mother also do not typically result in hemolytic disease of the newborn, as the mother's body is already sensitized to the Rh factor.
